Effects of Peer Vicarious Experience and Low Effortful Control on Children's Anxiety in Social Performance Situations

Two experiments investigated perceived and physiological changes in anxiety in children (7-11 years; N = 222; 98 female) in a performance situation after they observed another child in a similar situation with a negative or neutral outcome. The sample's London, United Kingdom, school catchment areas ranged from low to high socioeconomic statuses with 31% to 49% of children from ethnic minority backgrounds. In Study 1, participants watched one of two films of a child playing a simple musical instrument (a kazoo). In one film, an audience of peers responds negatively to the performance. In the other film, the audience response was neutral. Participants were then filmed playing the instrument themselves and measures of perceived and actual heart rate were taken along with individual differences in trait social anxiety, anxiety sensitivity, and effortful control. To better understand findings from Study 1, Study 2 replicated Study 1 but added a manipulation check and measures of effortful control and self-reported anxiety. Multiple regression analyses found watching a negative performance film, compared with a neutral one, was associated with a blunted heart rate response for children with low effortful control (Study 1 and 2). These findings suggest that children who are low in effortful control may disengage during performance tasks if the situation's social threat is elevated. Hierarchical regression analyses found that, compared to the neutral film, the negative performance film elevated children's self-report anxiety (Study 2). Overall, the findings indicated that anxiety in performance situations can be elevated after observing peers' negative experiences. Public Significance Statement These studies show that children's own feelings of performance-related anxiety are influenced by observing peers' experiences and poor self-regulation may alter how increased social threat is processed. Findings suggest negative experiences of peers in social contexts could contribute to children's anxiety development.
